PHY230B (Fall 20)
Quantum Theory of Fields

Instructor: Hsin-Chia Cheng (cheng [at] physics.ucdavis.edu)

Time & Place: Mon & Wed 9:00-10:20AM, Zoom link can be found on Canvas course site.

Office Hours: TBA through Zoom

Prerequisites: PHY230A

Website: http://cheng.physics.ucdavis.edu/teaching/230B-f20
Homework assignments and additional information can be found on the Canvas course page

Homework: Homework assignments can be found on the Canvas. Please turn in your homework at Gradescope.

Reader: TBA

Textbook: The recommended book is "An Introduction to Quantum Field Theory" by Peskin and Schroeder. However we will not follow the book exactly. The materials covered in this quarter roughly correspond to Chapters 4 (Sec 8), 5, 6, 7, 9, 15, 16 of Peskin and Schroeder. Some other useful books are

• Quantum Field Theory and the Standard Model, M. D. Schwartz
  
• Gauge Theory of elementary particle physics, Cheng and Li
  

Grading: There will be weekly homework assignments. Doing the problem sets is an extremely important part of learning. You can't learn the subject by just listening to the lectures without working through things by yourself. You can discuss the problem sets with your classmates, but you are not allowed to copy other people's homework. Each of you is required to write up your own homework following your own understandings. Each problem set is due about one week after its assignment in class.  The solutions will be available on the Canvas course website.  The homework will count 70% of the final grade. A take-home final will count 30% of the final grade.

Outlines of the course

• Quantum electrodynamics
  
• Introduction to radiative corrections
  
• Path integrals
  
• Non-Abelian gauge invariance
  
• Quantization of non-Abelian gauge theories
